VMore specifically the invention has for its -object to afford continuous lubrication in a valve of this character, -so as to effect more;

this application led September arranged between the ports' 20 are lubricant chambers or openings 21 extending length wlse of the valve, the walls of which are provided with enlarged portions 22 lfor this purpose. The lubricant chambers 2 1 are connected with the periphery ofthe valve by means of restricted openings or slots 23, while the vertical chambers 2l are connected at the bottom ofthe valve by a passage 24c. Y l

25 is a spring surrounding the valveistem Patented Jane ao, ieic.

20 and acting to hold the valve in proper relation in the body, the spring being retained l1n engagement with the valve by means of the cover 26 which is threaded upon vthe upper end of the bod 5. The cover 26 is Aprovided wit-ha threa ed dpening to receivev l a screw plug' 27 which A/engages a recess formed in vthe valve body, and serves to re'- tain the cap in 'proper relation totheJ valvel body, and to limit' the movement-ofthe valve in one direction. Operation ofthe valve-is limited by aA stop 29 carried by the valve stem and actin* to engage the aforef mentioned screw plug 27 when moved in one direction, vand a projection 28 when moved body ,whichv are constantly and thoroughly supplied with a proper amount of lubrication by reason of the fact that Athe discharges lubricatingA material extendl length-- Wise-o the valve plug to points adjacent its I vopposite ends, so that substantially' the-entire surfacefof theg valve vbody with which the plug comes in contact is .supplied with a practically constantv and even supply of lubricating material.v At ,the same time, there is no lchance for a surplus of lubricating material to .find anexit, or for any of -it tocome in contact with thel fluid passing vthrough the valve, as the discharge openings for the lubricant are so constructed and The lubricating material,l passes outyitsA arranged as to permit just enough of the lubricating material to pass therethrough to properly lubricate the wall of the valve body and to prevent any-of the lubricant from u@ 'tially coeXtensive with the plug.

2. The combination with a valve body, of a rotary plug arranged therein provided with lubricant chambers extending longitudinally of the plug and coeXtensive there- With, and connected with the periphery of the plug by means of restricted passages eX- tending longitudinally to points adjacent to the ends of the plug.
